10 Things We We Hate About Smart Car Key Fob Replacement
What Can a Smart Car Key Fob Do For You?
Known as fobs, keyless entry or smart keys, they were introduced by Mercedes in 1998. These computer-controlled fobs are capable of performing various tasks, such as locking and unlocking your car or getting it started.
They work by broadcasting an encrypted stream. This makes them less vulnerable to tech-savvy thieves.
Safety
A smart key fob communicates with vehicles through radiofrequency signals. It transmits a low-power message that, when pressed, will instruct the car to open doors and start its engine. The car recognizes the unique encrypted code from a particular key fob. This means that if the key fob is stolen, the car is unable to be started.
A new vulnerability allows thieves to exploit this method of communication. Relay attacks are based on devices that transmit on the exact frequency as the key fob. A burglar can put one of these gadgets in a pocket or hiding in a place to block the lock command from a distance, says How Stuff Works Electronics. This is a risk that may become more common as more motorists switch over to smart keys.
Aside from these security features, a smart key fob can make life easier by automatically taking care of the needs of your vehicle. A key fob that is connected to your smartphone, for instance can detect your presence and open the doors so you don't have to press the remote button. It could also detect that you're leaving the vehicle and automatically close it, so you won't forget to lock the doors. Many smart key fobs come with an indicator for the battery that alerts you in advance that the battery is at a low level. Most models allow you to replace the battery quickly and easily without any special tools.
Convenience
Smart keys are not required to be physically placed in an ignition slot to open or start the vehicle. BMW Group explains that the driver only needs to bring the key within the range of the car. In fact, some smart keys, like the Display Key, have an extremely small LCD touchscreen in color that allows drivers to access features like locking or unlocking and keyless start directly from their key fobs without needing to connect to the car's Bluetooth system.
Another way a smart key can save drivers time is by automatizing the process of locking their doors when they leave. Consumer Reports says that this feature is available on many automobiles. It also makes it easier for drivers to maneuver around tight spaces without accidentally hitting the door or something else.
G28CarKeys explains that smart key systems do not transmit the same frequency signal repeatedly in order to make them more vulnerable to relay attacks. As such, a stolen vehicle cannot be wired hot if it's equipped with a smart-key because the encrypted signal that the key fob transmits is unique to each car. This makes it extremely difficult for thieves to steal a car.
Security
Some of the latest electronic features found in the latest automobiles are contained in the key fob. These devices are capable of more than just locking and unlocking doors, or making chirping sounds to assist drivers locate their vehicle in parking lots. However certain owners might be unaware of the full capabilities.
Certain keys that are smart, for instance, will activate the auto windows and sunroofs of a vehicle when pressed. One auto editor at CR went into her Honda Accord to find the windows shut and the sunroof completely open. She was thankful for her Smart Key that automatically locked the car.
Some smart keys use computer-encrypted signals to thwart car thieves, according to How Stuff Works. This technology is able to prevent hotwiring where thieves steal the vehicle's engine control module (ECM) that is usually located on the front of the engine block. The ECM manages many essential functions including engine power, transmission control, and many more.
Smart keys also have anti-theft codes as well as a unique ID security code that is assigned to each key. This could stop ignition if the wrong key is used. The security ID is a specific code that's sent from the ECM to the key after it's placed into the ignition and then verified by a sensor inside the car.
Maintenance
Smart car key fobs can do much more than unlock the door. It can remotely start your engine, turn on the brakes and suspension and even start your vehicle. It can also provide details about your vehicle, like the level of fuel and oil temperatures.
A smart car key fob, just like every other electronic device requires regular maintenance in order to function properly. The majority of modern key fobs have battery indicators that warn the driver when the battery is low. It is simple to replace the battery, and you don't require special tools.
In certain instances the smart key might stop working completely. If you suspect this is the issue try resetting the smart key after leaving the vehicle, then returning inside. This will allow the car to know that the key fob is still in the vehicle and will allow it to regain its functionality.
Get in touch with a locksmith if are not able to get your key fob to function. They can reprogram it so that the car can recognize it once more and allows you to use all of its features. This is usually cheaper than buying a new fob and can save you money over time. In some instances, a locksmith can even fix an existing fob in order to be used to make new keys. This could save you more money in the long run.
